Free Text Diff Checker – Compare Texts Online

Green highlights show text that was added, red highlights show text that was deleted, and yellow marks lines that were modified. This color coding lets you scan the comparison quickly and understand at a glance what changed between the two versions of your text.

Yes. Helperzy Text Diff works with any plain text, including code in languages like HTML, CSS, JavaScript, Python, and configuration files. It highlights changed lines and the specific words within them, which makes it handy for reviewing edits between two versions of a script or config.

It compares line by line to find which lines changed, and within changed lines it highlights the specific words that differ. This two-level approach makes it easy to see both which lines were edited and exactly what changed inside them.

Yes. Paste your original version on the left and the edited version on the right, and the tool highlights every insertion and deletion. This is a fast way to review changes a collaborator, editor, or client made without re-reading the whole document.
